分析简单句子
smoking,it is believe ,is responsible for 30 per cent of all deaths from cancer .请问 ,it is believe ,是句子的什么成分?

-- - - ,it is believed ,- - -- 是插入语成分。

== It is believed that smoking- - - -主语从句
== What is believed is that smoking - - -主语从句+表语从句
==Smoking being responsible- - - - is believed. 动名词做主语
== As is believed, smoking is - -- - 插入语结构,但也有人说是定语从句

是句子的插入语

应该是it is believed吧?
意译:吸烟,据(人们)认为,是因癌症而死亡的所有人数中三成的死因.
it is believed为句子的独立成分,视为插入语.

比较正常易看懂的顺序是It is believed that smoking is responsible for 30 per cent of all deaths from cancer .
但是此句没有用这样的语序,而是把我写的这个句子的宾语从句中的主语作了整个句子的主语,it is believed则成了插入语的成分一般来说,插入语都会与用逗号隔开。
ps,插入语是句子中的一种独立成分,拿掉对句子不影响。
